UNITED STATES PATENT (")Fi-IonE HENRY YV. SIMMS, OF BAY CI'IY, MICHIGAN.

VALVE.

SPECIFICATION forming part of Letters Patent No. 340,630, dated April27, 1886.

Application filed August 2G. 1885.

To aZZ whom it may con/cern:

Be it known that I, HENRY XV. SIMMs, a citizen of the United States,residing at Bay City, in the county of Bay and State of Michigan,haveiuvcnted certain new and useful Improvements in Valves; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and gures of reference markedthereon, which form a part of this specification.

My invention relates to valves or cocks of the class used in fluid orgas pipes; and it consists, chiefiy, in the combination and arrangementof the different parts thereof, as I shall hereinafter more fullydescribe and claim; and the object of my invention is to construct avalve or cock which can be easily made and repaired, and that may, bymeans of packing, be rendered free from the leakage and wear of ordinaryvalves, and to provide a means by which water remaining in the pipesafter the valve is closed will drip or run out therefrom and avoid thedanger of bursting from the action of frost. I accomplish these objectsby means of the device illustrated in the accompanying drawings, inwhich Figure l is a horizontal sectional view of my improved valve,showing the passage open. Fig. 2 is the same with the passage closed.Fig. 3 is a longitudinal vertical section of Fi 0. l. Fig. 4 is atransverse section of thesame.

Silnilar letters referto similar parts th ron ghout the several views,

a represents a hollow casing, with the side openings, c, opposite eachother and provided with pipe-connections. The lower end of this casingis closed by a plug, 7c, the inner side of the plug being provided witha circular' recess, w, into which is placed the packing-ring f, ofrubber or other suitable material, and the side walls of the easing areprovided on their inner sides with the longitudinal grooves a, intowhich are placed and properly secured the packing-strips 7i. Thesestrips h are so constructed that the outer-surface thereof is concave,to nearly conform to the plane of the inner surface of the walls of thecasing, but

arranged, however, to project at one edge to Serial No. 175,356, (Nomodel.)

a short distance beyond the walls of the casing. as at r.

Vithin the cz sing a is placed a valve, d, consisting of the centralpart, g, having the Wings s extending entirely across the inner openingof the casing. The circular diskf is secured to the lower end of theparts d and s and rests upon the packing ring a, the central partextending into the plug k, and a similar disk, e, is secured to theupper ends of the parts d and s, while the smaller portion p eX- tendsout of the open end of the casing, and is arranged with a means ofrotating the valve Within the casing; Above and resting upon the disk eis the packing-ring` i', and surrounding the upward-extending part hf,and screwed into the open endof the casing a, is the gland b. This glandI) is arranged with a recess, n, into which the packing-ring fi rests,and the packing-strips h extend beyond the paeking-rings'. and a, sothat when the gland is screwed down upon the ring i the valve is forceddown upon the ring a, pressing the rings and strips /L firmly togetheras well, and forming a packed joint between all the parts. The val ve isthen turned to the position shown in Fig. 2, bringing the wings s tobear firmly against the packingstrips 71, and the opening will beperfectly closed, and should any unevenness or wearing away of the partsoccur the valve may be turned farther around, when the project-ingportion o of the packing-stri ps will bear against and fill up or closethe opening produced by the imperfect edges of the wings s, and whengreatly worn the valve may be easily removed and the packing strips orrings be replaced with small cost or trouble.

Through the lower disk, 91 is arranged an opening, my, and a similaropening7 o, is made through the plug k, the opening o being located nearone-of the openings c, and the opening m is placed in such a position asthat when the valve is turned for closing the way, as in Fig. 2, theopeningm will bejust over the opening o, so that when water is passingthrough the valve in the direction of the arrows, and the Valve isturned to shut oi'f the ilow, the water that is beyond the valve willdrip or run out through the openings m and o, and when the valve isturned to allow the water to pass the valve the opening o will be shutsi?,

so that no Water can pass through it. A drippipe, t, may be attached tothe opening o for conducting away the drip from the valve, and

tending part p, the paekingrng u below and I5 the packing-ring z' abovethe valve, in combination with the packing-strips 7L within the saidgrooves u, and arranged with the part v projecting beyond the plane ofthe inner snrfaee ofthe easing, substantially as and for the 2o purposeset fort-h.

In testimony whereof I affix my signature in presence of two Witnesses.
